Nanotechnology is the branch of engineering that deals with technology carried out on a scale of less than 100 nanometers. In which, the goal is to control individual atoms and molecules. Nanotechnology is used in space, medicine, cosmetics, and air purification.
Nanotechnology used in space
Space:
Nanotechnology may hold the key to making space-flight more practical. Advancements in nanomaterials make lightweight spacecraft and a cable for the space elevator possible. By significantly reducing the amount of rocket fuel required, these advances could lower the cost of reaching orbit and traveling in space.
Nanotechnology working in medicine.
Medicine:
Scientists have used nanotechnology to develop a new type of bone construction. By simply engineering the components that real bone is made from, these nanoparticles create bone growth that is identical to natural bone both in structure and composition.
Cosmetics:
Nanotechnology that is used in cosmetics has the ability to go deep into the skin and moisture. It also can heal the skin tissue. It is also used in shampoos, sun-screens, and anti-aging products.
Better Air Quality:
Nanotechnology can enhance the performance of catalysts used to change vapors leaving from cars or industrial plants into toxic gases. Due to the catalysts made from nanoparticles have a larger surface area to interact with the reacting chemicals than catalysts made from larger particles. The larger surface area allows more chemicals to interact with the catalyst simultaneously, which makes the catalyst more effective.
Uses of silver nanoparticles:
Silver nanoparticles
Silver nanoparticles have the ability to clean water.
They can also kill bacteria from any material that was previously stored in the bins, thus minimizing health-risk from harmful bacteria.
All bacteria use an enzyme as a form of ‘chemical lung’ in order to metabolize oxygen. Silver ions from the silver nanoparticles weaken the enzyme and stop the take up of oxygen. This effectively suffocates any bacteria, killing it within 6 minutes and leaving surrounding tissue or material unaffected.
With the help of silver nanoparticles, body tissue can be reproduced or restored, which eventually could lead o the substitution of organ replacements to the repairing of organs.
All silver nanoparticles have the ability to kill bacteria.
Drawbacks of Nanotechnology:
The manufacturing of nanotechnology is extensive and difficult-very difficult to maintenance the culture and synthesizing time are very high, making the development of the process costly. It has the ability to replace natural substances, resulting in the job loss of those who produce natural substances. Nanoparticles in the body may trigger allergic reactions and the negative response of the immune system.
